The dissertation thesis is focused on increase of the efficiency of production processes in Czech companies, whose main work focus is electric motor production with usage of the lean manufacturing tools with the environmental management system. The main reason for choosing this topic were results of prime study of the target group of companies which has proved that companies do have trouble not just with integration but especially with implementation of the lean manufacturing methods. This is the reason why concrete conditions and basic principles need to be defined to show how to proceed. The objective of this dissertation thesis is to suggest the model of integration of lean manufacturing tools with optional environmental management tool and as the lean manufacturing tools were chosen methods of lean management in production and as an optional environmental tool was chosen system of environmental management based on norm ISO 14 001. For this area of interest the primary and secondary research was used. Based on knowledge from detailed research of Czech and foreign literary sources a survey and guided interview was started with companies, which are focused on electric motor production. The thesis contains a detailed evaluation of empirical research with testing of stated hypothesis, based on which the verbal model of the integration of the lean manufacturing tools with the environmental management system is assembled. The implantation based on the suggested verbal model of the integration in the company should lead not just to the relationship improvement between the company and the environment but also to better understanding of the relationship of two independent kinds of company management leading to saving money, working environment improvement, productivity increase or ecological onus decrease. The benefits can be seen in theoretical, practical and also pedagogical level.
